-LRB- CNN -RRB- -- Juventus came from behind to defeat Bologna 4-1 on Saturday to put pressure on Inter Milan at the top of the Serie A table .

Alessandro Del Piero celebrates the first of his two goals in Juventus ' 4-1 victory over Bologna .

Massimo Mutarelli put Bologna ahead in the 24th minute , but a dominant second half display from the Bianconeri gave them all three points .

Hasan Salihimidzic equalised in the 49th minute before Sebastian Giovinco put the home side ahead in the 71st minute .

A brace from Alessandro Del Piero in the 75th and 88th minutes sealed a win which takes Juve to within four points of leaders Inter , who face a tricky home match against Fiorentina on Sunday .

In Saturday 's other match , Genoa boosted their hopes of playing in the Champions League next season thanks to a 1-0 win at 10-man Cagliari to move above Fiorentina into fourth place .

Cagliari lost Andrea Cossu to a red card in the 39th minute but held out until five minutes from the end when Ruben Olivera grabbed the decisive goal .

Meanwhile , veteran striker Filippo Inzaghi scored his 300th career goal to help Milan crush Siena 5-1 on Sunday to consolidate third place in the table .

The 35-year-old scored twice , while Alexander Pato also netted a brace and Andrea Pirlo scored the opener from the penalty spot , as Milan proved too strong for their opponents -- for whom Massimo Maccarone was on target .

Roma lost further ground in the race for the fourth Champions League place as they were held to a 2-2 draw at Sampdoria .

Julio Baptista gave the visitors a seventh-minute lead but Giampaolo Pazzini headed home an equalizer before the same player put the home side ahead after a mistake from goalkeeper Doni .

But Baptista levelled from the spot after Marco Padalino was penalized for fouling Max Tonetto -- the player who missed the decisive spot-kick in the midweek Champions League defeat by Arsenal .
